MP26060
1A Linear
Li-Ion Battery Charger with Trickle Charge
DESCRIPTION
The MP26060 is a linear, high-performance
single cell Li-Ion battery charger. By integrating
high voltage input protection into the charger IC,
the MP26060 can tolerate an input surge up to
24V.
The device features constant current (CC) and
constant voltage (CV) charging modes with
programmable charge currents (85mA to 1A),
programmable battery full threshold, thermal
protection, battery temperature monitoring,
reverse current blocking, and trickle charge.
The device also provides AC adapter power
good and charge status indications to the
system.
MP26060 is available in a 10-pin 3mm x 3mm
QFN package.
